From 6d44610f8321a9aa3bc408026f888872b1390712 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 22 Aug 2012 16:00:40 +0300 Subject: [PATCH] OMAPDSS: DSI: Add FEAT_DSI_PLL_REFSEL Add FEAT_DSI_PLL_REFSEL. OMAP5's DSI PLL needs configuration to select the reference clock to be used. We always use SYSCLK.
